The Delta variant spreads like chickenpox: “Even vaccinated people transmit it”

The Delta variant of CoronavirusSars-CoV-2 causes more severe disease than the other variations previously discovered and spreads as easily as chickenpox. Not only that: the data show how fully vaccinated as well as unvaccinated people can transmit it. The alarm comes from an internal presentation by the Centers for Disease Control and Prevention released by the Washington Post and the New York Times. Rochelle P. Walensky, director of the CoC acknowledged that Delta is more transmissible than the viruses that cause Mers, Sars, Ebola, colds, seasonal flu and smallpox. For this, the agency claims, the war on Coronavirus has changed and a new report is expected for Friday.

Delta variant and chicken pox: the alarm in the United States

The CoC therefore recommend that everyone use the mask in public environments and under certain circumstances. The study also shows that with the variant of the virus in circulation, the risk for the elderly of ending up in hospital or dying compared to younger people is greater regardless of whether they are vaccinated or not. Another study estimate states that there are 35,000 symptomatic infections per week among the 162 million vaccinated Americans. The new data seems to highlight that vaccinated people are spreading the virus like unvaccinated people, albeit to a lesser extent. Transmission from the immunized, according to Walensky, is a rare event but according to other scientists it may be more common than previously thought.

For this reason, according to the CoC, even the vaccinated must wear masks indoors where the transmission of the virus is greater. And people with weak immune systems should always wear them instead. Just as that slice of the population that is in daily contact with children, the elderly or vulnerable people should be vaccinated. The infection caused by the Delta is 10 times higher than that of the Alpha, which is however highly contagious. The document is based on an analysis of an outbreak in Provincetown, Mass., Which began after July 4 and grew to 882 cases: 74% of the positive swab tests had been vaccinated.

Symptoms of the Delta variant

The study states that people infected with the Delta variant have huge amounts of the virus in their nose and throat, regardless of vaccination. And Delta infection is more likely to lead to serious illness and hospitalization, even in intensive care. But vaccination still protects against the worst outcomes: Vaccines are highly effective in preventing serious illness, hospitalization and death. Anthony Fauci, a White House adviser on the Covid pandemic, also said yesterday that vaccines do not protect 100% from contracting the infection. The protection is in fact estimated at 88.5% after two doses by the Higher Institute of Health. Vaccines, however, highly prevent severe forms of the disease.

“No vaccine is 100% effective, because the virus has changed – explained Fauci in an interview -. The data on the Delta mutation that we have available today show that the level of infection in the mucous membranes in a vaccinated person is the same as that in an unvaccinated person “but in those who are vaccinated” the risk of the disease manifesting itself in a severe form is lower. It is extremely rare that a vaccinated person, even if infected, ends up in hospital ». For this reason, the immunologist has repeatedly reiterated the appeal, “it is necessary that the majority of people get vaccinated”. Fauci, in a subsequent intervention on 27 and 28 July, stated however that this circumstance is to be considered a “rare event”.
